Migrating from Xen 3.2 to KVM
Hello,
I currently (I think) have XP installed on an LVM
volume /dev/mapper/vol_group1-windows. I have been trying to power this VM up on KVM (Ubuntu 8.10 dropped Xen). Come to think of it I am not even sure if the on disk format KVM expects is the same the Xen wrote to disk.
What is the likely hood that I will succeed?
At this time using the attached config file I boot up into the windows boot strap. I immediately hit the safe mode menu. Once I step pass the safe mode menu then the vm reboots. Known problem?

Hi Mike
Did you use some Xen specific driver in the image? If so, that's a problem... You can post dmesg here also.

From the description above, I think you are using KVM distributed by Ubuntu? I
checked KVM version from Ubuntu upstream, seems it's kvm-72, and now it's kvm-82... You can refer to http://kvm.qumranet.com/kvmwiki/HOWTO1 to try new KVM release.

Ubuntu recently updated their KVM docs, maybe some hints in there:
https://help.ubuntu.com/community/KVM
Also, Boris has some Ubuntu Xen Howtos, if you are simply looking to upgrade Xen.

Hope that helps.

If you're using an lvm volume. the on-disk format is the same.

I'm surprised it failed -- kvm and Xen use the same device model (qemu) so they should be highly compatible.

Anything interesting in dmesg? Any Xen specific drivers installed?

I have a truly marvellous patch that fixes the bug which this signature is too narrow to contain.
